Enhancement: support instanceName filtering for kubernetes auto-discovery deployment

[atropos112]

Proposed change

Add another annotation to kubernetes discovery to allow user to specify for which instance is this supposed to be present for. If no instance provided then it works for all instances preserving current behaviour.

Closes #2487

• New service widget
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Documentation only

This certainly looks like it would work but double-checking, did you actually test it?

[atropos112]

You are too quick for me 😉 I have now done testing and can confirm it works.

My testing was to build the image deploy on my cluster and see

• having instance annotation matching my instanceName -> I can see it just fine (as expected)
• having instance annotation not matching my instanceName -> I can't see it (as expected)
• not having instance annotation -> I can see it just fine (as expected)

I have tested it on vivaldi (chrome based) and firefox, but I would be shocked if this is browser based

Ha, sorry about that—no rush, but looks good =)
